This aquifer is characterized by sand, clay and sandy-clay sedimentary facies and the Manaus sandstones, deposited in the fluvial and fluvial-deltaic ambient. An estimated amount of 32.500 km3 of groundwater can be exploited from this aquifer through wells of about 220 m deep, producing water at a maximum rate of 300 m3/h. However, there are big distortions in the production rates. In some boreholes they are as low as 78 m3/h because of wrong filter locations due to the lack of information about the aquifer position in depth. The permo-porous zones forming the aquifers were mapped in the northern and eastern part of the town of Manaus, employing in integration of the information available from the well-log geophysical data, Vertical Electrical Sounding (VES) data the litology obtained through the examination of the borehole cuttings. This work resulted in the identification of two distinct geohidrological zones in depth. The first, up to the depth of 50 m, is marked by clay, sand and sandy-clay zones of varied dimensions. However, they are not recommended for great demand of water because of the limited lateral extension of the sand zones and for being susceptible to superficial contaminations. The second zone extents below 50 m to about 290 m in depth, and is very appropriate for the storage of large amount of groundwater because it contains thick sand zones of great lateral extensions. The production rate of the wells in this aquifer is around 300 m3/h. Therefore, it is recommended for the supply of good quality groundwater to meet higher demands such as for a district in a town. An analysis of the transverse resistance and longitudinal conductance maps of the upper zone up to 50 m, leads to that NE and SW sectors of the area contend more permeable zones, contend less clayey layers, therefore, of higher transmissibility zones of the aquifer system. However, for wells deeper than 50 m, recommend NNW e SW region for their locations based on the results obtained through Geophysical Well Logging that delineates the permo-pourous layers forming a good aquifer.porAcesso AbertoAquíferosÁguas subterrâneasPerfilagem geofísica de poçosManaus - AMAmazonas - EstadoAmazônia brasileiraMapeamento de aquíferos na cidade de Manaus (AM) utilizando perfilagem geofísica de poço e sondagem elétrica verticalDissertaçãoCNPQ::CIENCIAS EXATAS E DA TERRA::GEOCIENCIAS::GEOFISICA::GEOFISICA APLICADA
